It was discovered by Mehler in 1951 that in the presence of excess catalase and ethanol, oxygen is consumed by the chloroplast preparation upon illumination and a stoichiometrical amount of CH_3CHO is formed at the same time. This reaction is generally referred as"the Mehler reaction" and is a variation of the Hill reaction with molecular oxygen as oxidant. Recent investigations have shown that in the Vit. K or FMN-mediated photophosphorylation, ATP formation is accompanied by ~(18)O exchange. Hence, an intimate...

It was discovered by Mehler in 1951 that in the presence of excess catalase and ethanol, oxygen is consumed by the chloroplast preparation upon illumination and a stoichiometrical amount of CH_3CHO is formed at the same time. This reaction is generally referred as"the Mehler reaction" and is a variation of the Hill reaction with molecular oxygen as oxidant. Recent investigations have shown that in the Vit. K or FMN-mediated photophosphorylation, ATP formation is accompanied by ~(18)O exchange. Hence, an intimate connection may exist between these two separately discovered reactions of isolated chloroplasts.In the present paper the activities of the Mehler reaction and photophosphorylation of isolated wheat-seedling chloroplasts were simultaneously determined. The principal results were as follows:(1) Among the catalytic cofactors of photophosphorylation, Vit. K and FMN do, whereas PMS does not, enhance the Mehler reaction(Table 1).(2) A parallelism is found between the rates of ATP and CH_3CHO formation in the presence of Vit. K or FMN and also in the absence of added cofactor. The P/O value thus obtained is twice that of simultaneously determined K_3Fe(CN)_6 system and amounts to 2 when the coupling is complete(Table 2, 3).(3) The effects of pH, NH_4~+ and aging of chloroplasts on the Vit. K and on K_3Fe(CN)_6 systems are similar with respect to electron transport and phosphorylation(Fig. 1).(4) Under aerobic condition the P/O value remains practically unchanged upon varying the concentration of the cofactor(Fig. 2).The results of the present investigation showed that the same processes are involved in the Mehler reaction and photophosphorylation mediated by Vit. K or FMN. That the Vit. K or FMN mediated photophosphorylation is actually non-cyclic (?)n nature is conclusively proved. These cofactors are in fact"Hill oxidants" reversibly oxidized by molecular oxygen. Their possible physiological role in the photosynthetic process was briefly discussed.

我們同时測定了小麦离体叶綠体的Mehler反应与光合磷酸化作用,結果指出: 1.光合磷酸化輔助因素Vit.K及FMN促进Mehler反应,PMS无影响。2.离体叶綠体不加輔助因素或加入Vit.K或FMN的情况下,ATP与CH_3CHO的形成量有一定的数量关系。由此算出的P/O值約为同时測定的K_3Fe(CN)_6系統的P/O值的二倍。在偶联得完全的制剂中,P/O值达2。3.无論对电子传递还是磷酸化作用,pH、解联剂(NH_4~+)及叶綠体保存时間对Vit.K及K_3Fe(CN)_6系統的影响均有一致的趋势。4.在有氧条件下,P/O值与輔助因素的浓度无关。本文結果指出了Mehler反应与FMN或Vit.K导致的光合磷酸化实际上发生在同一个过程中,这样就进一步肯定了Vit.K与FMN导致的光合磷酸化都是属于非循环方式。对它們在生理上的可能作用也作了簡短的討論。

If one deals with a practical system, arising out of physics or technology, it is quite certain that perturbations will come up which are expressed not only in terms of initial conditions other than x=0 but also, and above all, in terms of the exterior and adventitious actions, for example fairly brusque impulses, etc, This problem is termed by G. N, Dubosin as that "stability in the case of constantly acting disturbances"[2]or"stability under persistent distur-bance". Simple sufficient conditions for such stability...

If one deals with a practical system, arising out of physics or technology, it is quite certain that perturbations will come up which are expressed not only in terms of initial conditions other than x=0 but also, and above all, in terms of the exterior and adventitious actions, for example fairly brusque impulses, etc, This problem is termed by G. N, Dubosin as that "stability in the case of constantly acting disturbances"[2]or"stability under persistent distur-bance". Simple sufficient conditions for such stability have been obtained by I. G. Malkin[3].In this paper, we consider the necessity of Malkin's conditions in quite general case and prove that for the particular case of two dimensional autonomous systems, assumed analytic, the malkini's conditions are necessary.The author finds that Theorem Ⅳ in Malkin's article is erroneous. Thus, many counter examples are constructed for showing that the stability under persistent disturbance may happen in a system which is stable but not asymptotically stable in the sense of Liapunov.The principal result may be extended to n-dimensional autonomous systems. Further, criterion for unstability under persistent disturbance is given.

本文报导了作者对铬镍奥氏体不锈钢焊缝中铁素体含量的磁法测定的研究结果,包括在饱和磁场中的冲击测量法,在不饱和交变磁场中的测量方法以及有关选择标准试样的一些问题的讨论。详细介绍了冲击测量法的基本原理、所用装置及测量方法。焊制、并用此法测定了一批铬镍不锈钢焊缝的铁素体标准试样。试制了具有不饱和交变磁场的便携式铁素体测定仪,与不锈钢标准试样相配合,可以迅速简便地测出试样中的铁素体含量。根据理论分析及实际试验结果,论证了国内外所沿用的以纯铁和铁粉代替不锈钢作为标准试样的方法是不正确的。
